Think 30 vs DKB Vanity Specs

included components

Edge: DKB Alenza 42-Inch Gray Marble Vanity

The DKB Alenza arrives as a complete unit, including the vanity base, a countertop, and a pre-installed sink. You get a fully functional bathroom station right out of the box. In contrast, the Think 30 is listed as a freestanding base cabinet only. It does not include a countertop or a sink in its standard configuration. This means you must purchase those items separately if you choose the Think 30. For buyers who want a turnkey solution without sourcing additional parts, the DKB package offers immediate convenience and a cohesive look from the start.

sink configuration

Edge: DKB Alenza 42-Inch Gray Marble Vanity

Sink integration is a major differentiator between these two options. The DKB Alenza features a single left-rectangular undermount sink made from genuine Italian Carrara marble. This stone countertop has a 1.5-inch edge and is polished for a refined finish. The Think 30 data does not list any sink or countertop material, as it is sold as a cabinet base. If you need a vanity with an integrated basin, the DKB provides that essential component. The Think 30 requires you to source a compatible top and sink separately to complete the setup.

number of drawers

Edge: DKB Alenza 42-Inch Gray Marble Vanity

Storage organization differs significantly in the drawer department. The DKB Alenza includes four full-extension dovetail drawers, plus two soft-closing doors and a decorative faux drawer for additional utility. This provides ample room for organizing toiletries and linens with smooth operation. The Think 30 offers two standard drawers, one tip-out drawer for small items, and a cabinet section with shelves. While the Think 30 has a tip-out option for small items, the DKB provides more traditional, full-size drawers for larger storage needs.

mounting type

Edge: Think 30 30 Inch Grey Solid Wood Vanity

Installation style is another key consideration for your bathroom layout. The Think 30 is explicitly designed as a freestanding unit. It sits directly on the floor, allowing for easy placement and potential movement. The DKB Alenza also functions as a freestanding piece, but its substantial size and weight require careful positioning. Both units avoid the need for wall mounting, which simplifies the installation process. However, the Think 30 is lighter and smaller, making it potentially easier to maneuver into place compared to the heavier DKB model.

build and weight

Edge: DKB Alenza 42-Inch Gray Marble Vanity

The physical presence of each vanity affects stability and durability perceptions. The DKB Alenza is significantly heavier at 208 pounds, reflecting its solid wood construction, marble top, and larger dimensions. It measures 43 inches wide and 36 inches high. The Think 30 weighs 102 pounds and measures 30 inches wide by 33.8 inches high. Both use solid wood frames, but the DKB includes engineered wood panels for a smooth surface. The Think 30 features a water-resistant paint finish on its doors and drawers. The DKB offers a more substantial, premium feel due to its mass and materials.
